Embodiment
As shown in Figures 2 and 3, be an embodiment of cartridge of the present utility model, cartridge is used in image processing system, such as, in the developer of printer or duplicating machine etc.The cartridge of the present embodiment comprises rotary container main body 1, and rotary container main body 1 is in order to hold carbon dust, and it can rotate around its axis under the driving of the rotary driving part of developer.
As shown in Figures 2 and 3, the end of rotary container main body 1 is provided with toner discharge parts 2, toner discharge parts 2 comprise cylindrical section 20, and one end of cylindrical section 20 is connected with rotary container main body 1, and the other end is connected with end cap 21.Cylindrical section 20 has toner discharge hole 201, carbon dust can flow to cylindrical section 20 by rotary container main body 1 and is discharged into the carbon dust receiving unit of image processing system by toner discharge hole 201.Toner discharge hole 201 can arrange multiple, and toner discharge hole 201 can be designed to the strip hole extended along the circumference of cylindrical section 20.End cap 21 has and to be stretched out the collecting parts 22 formed by end cap 21, for coordinating with drive disk assembly 5.
The toner discharge hole 201 of toner discharge parts 2 just can be opened when cartridge loads in developer, is sealing when not using.Therefore, in toner discharge parts 2, be provided with seal member 3, seal member 3 is arranged in cylindrical section 20, by moving axially the toner discharge hole 201 opened or closed on cylindrical section 20.Concrete, in this enforcement, seal member 3 comprises a ring part 30 and the sleeve pipe 31 coaxial with ring part 30, and by the anatomical connectivity of sprag fashion between sleeve pipe 31 and ring part 30, ring part 30 can seal or open toner discharge hole 201 when seal member 3 moves axially.Seal member 3 relies on the driving of seal member driving stem 4 and movement, seal member driving stem 4 can be shaft, such as in this enforcement, it is a round bar, one end of seal member driving stem 4 is penetrated in cylindrical section 20 by end cap 21 and is also connected with seal member 3, end cap 21 has the first through hole passed for sealing parts driving stem 4.
In the present embodiment, cartridge also comprises drive disk assembly 5, and drive disk assembly 5 is slidably connected in the collecting parts 22 of toner discharge parts 2, and collecting parts 22 can be followed this driver part 5 and be rotated, thus driven rotary container body 1 rotates together.As shown in Figures 4 to 6, the elastic arm 52 that drive disk assembly 5 comprises discoidal base portion 50 and extended to form vertically by the edge of base portion 50, elastic arm 52 comprises cylinder 521 and hooks shape projection 522, and the end of cylinder 521 is formed and hooks shape projection 522.Hook shape projection 522 comprises a bottom surface 523 relative with base portion 50, and the angle β between bottom surface 523 and cylinder 521 is obtuse angle.
As shown in Figures 3 to 6, base portion 50 is provided with the second through hole 502 passed for seal member driving stem 4, the inwall of the collecting parts 22 of toner discharge parts 2 is provided with the fin 221 extended vertically, the periphery of base portion 50 is provided with the chute 501 coordinated with fin 221, fin 221 can have multiple, and chute 501 is also corresponding is multiple.When toner discharge parts 2 coordinate with drive disk assembly 5, fin 211 inserts in chute 501, and such drive disk assembly 5 is spacing mutually in circumference with resettlement section 22, and collecting parts 22 are followed drive disk assembly 5 and rotated together.
As shown in Figure 4 and Figure 5, the axial direction of base portion 50 is provided with tabs 53, and the shape of tabs 53 is broken line shape, and is distributed in symmetrically between two elastic arms 52, and tabs 53 can strengthen the physical strength of drive disk assembly 50.As shown in Figure 7, be the vertical view of another drive disk assembly that the present embodiment provides, the shape of tabs 530 is set to " W " shape.
The original state of cartridge, when not namely being encased in image processing system, the toner discharge hole 201 on toner discharge parts 2 seals by the ring part 30 of seal member 3, and drive disk assembly 5 is enclosed within seal member driving stem 4 by the second through hole 502.
Cartridge is when being installed to image processing system and being inner, and the elastic arm 52 of drive disk assembly 5 can be fastened on the rotary driving part of image processing system.As shown in Figure 8, rotary driving part 6 is arranged in image processing system, rotary driving part 6 comprises a ring wall 60 and the driving shaft 61 coaxial with ring wall 60, ring wall 60 and driving shaft 61 can pass through together with floor or end disc anatomical connectivity, ring wall 60 has the coupling aperture 601 that the circumference along ring wall 60 extends, coupling aperture 601 can be one, also can be multiple, be preferably two, make elastic arm 52 stressed more even.After drive disk assembly 5 is subject to axial expulsive force, the hook shape projection 522 of elastic arm 52 can be fastened in coupling aperture 601, thus rotary driving part 6 is connected with drive disk assembly 52, now, the driving shaft 61 of rotary driving part 6 promotes seal member driving stem 4 and seal member 3 is moved axially open toner discharge hole 201.When rotary driving part 6 rotates, the end of coupling aperture 601 promotes to hook shape projection 522, makes drive disk assembly 5 accept to make drive disk assembly 5 follow rotary driving part 6 from the driving force of rotary driving part 6 and rotates.When cartridge removes in developer, when drive disk assembly 5 is subject to axial after the power in rotary container main body 1 direction, as shown in Figure 6, because the angle beta between the bottom surface 522 of drive disk assembly 52 and cylinder 511 is obtuse angle, therefore hook protruding 522 of shape to depart from coupling aperture 601, thus complete being separated of cartridge and rotary driving part 6.
In the present embodiment, conveniently the coordinating of driving shaft 61 and seal member driving stem 4, the end that seal member driving stem 4 coordinates with driving shaft 61 is provided with pit, and the end of driving shaft 61 is then set to taper shape.
As shown in Figure 2, in the present embodiment, cartridge also comprises a protective cover 7, and there is internal thread protective cover 7 inside, and rotary container main body 1 is provided with external thread, and before cartridge is not sealed off, protective cover 7 can play the effect of protection cartridge.In the present embodiment; cartridge can also comprise a tearing member; tearing member circumference is wrapped on the carbon dust escape hole of cylindrical section; when sealing off cartridge; first protective cover 7 being taken off from rotary container main body 1, then manually can tearing the parts for sealing toner discharge mouth that cylindrical section wraps up.
As shown in Figures 2 and 3, in the present embodiment, cartridge also comprises an annular projection 202 arranged along cylindrical section 2 circumferential direction, annular projection 202 can with the component snaps in image processing system, thus limit the axially-movable of rotary container main body, facilitate opening of carbon dust escape hole, and when rotary driving part 6 drives cartridge to rotate, run more steady.
Finally it is emphasized that the utility model is not limited to above-mentioned embodiment, also should be included in the protection domain of the utility model claim as the change such as by bolt, the mode such as to be threaded drive disk assembly being fixed in collecting parts.
